in the accompanying drawings iilustr ing the preferred form oi my invention as o cieteci with motorcycle, as an exmnpfie, Figure 1 is an elevation of generator supported from the frame of the cycle and arranged to be driven by frictional engagement with the tire; Fig. 2 is e iongitudinui cei'itrei section of the generator at rightengles to Fig. 1, Fig. 3 is a section on line 3--3 of Fig. 2; Fig. 4i. is e, fragmentary cletsi View particularly showing the manner in which the bearing member abuts the ends of the magnet arms.

The generator is of the magneto typo he ving a one-piece permanent field n'uignet a Without any attached pole pieces. The mag net 11 an inner cylindricel-shaped face with its axis of curvature eiong the length of the arms of the mugnet, that is cm the poles toward the arch between the arms. While the outside surface of the magnet is similarly curved hut has flat surfaces along the sides adjacent the openings between the arms. Thus the magnet has a substantially annular shape in cross section with int surfaces along its outer sides, shown in Fig. 5.

The armature is of the shuttle ound type with its periphery eperutecl by a small air gap from the inner face of the magnet arms. The friction roller m is fastened on the outer end of the armature shaft (Z in frictional engagement with the tire. so that the armature is driven at comparatively hi s eed relatively to the speed (iii the motor-c cle. By simply remov-- the screws I72, the magnet a may he With- (lrznvn from around the armature and the generator inspected and repaired.

The generator is supported from the frame .9 of the motor cycle by a clip 9 fustcned by :1 screw 9"- to the end of abracket arm p which is provided With an eye '0 at the other curl. The bearing (Z has an ex tension terminating in an eye w. The bolt u having the Winged nut If extends through disclosed may be embodied in various forms wnet arms and constitutes securely I of magneto electric generators within the scope of my invention, and that the generator may be used for lighting or other purposes in association with other forms of moving vehicles, or for stationary use.

Having thus described my invention, what I claim is 1. In a magneto electric generator, a permanent field magnet of the horseshoe type, a bearing member abutting the outer ends of the magnet arms, an armature rotatable between the poles of the magnet on an axis along'the length of the magnet arms and having a shaft extending from one end only to entirely support the armature in overhung position from the bearing member, fastening means holding the bearing member rigidly against the magnet, and means on the shaft whereby the armature may be rotated.

2. In a magneto electric generator, a permanent field magnet of the horse-shoe type, a rotatable armature having its axis positioned along the length of the magnet arms, an armature bearing member located at the outer ends of the magnet arms and having adepending flange in smooth surface contact with the magnet arms, a plate fastened to the magnet and to the bearing member so that the latter holds the armature in centered position between the poles of the magnet, and means whereby the armature may be rotated.

3. In a magneto electric generator, a permanent field magnet of the horse-shoe type .having an inner cylindrical face with its axis ofcurvature along the length of the magn t arms, an armature having its axis coincident with said axis of curvature, an armature bearing member abutting the outer ends of the magnet arms'and having a depending circular flange in smooth surface -=eontact with side faces of the magnet arms, said bearing member forming a closure for the end ofathe magnet and positioning the armature in centered position between the poles of the magnet, plates fastened to the magnet over the space between the arms thereof forming side closures therefor and also fastened to the bearing member holding it rigidly in place, and means whereby the armature may be rotated. 4.
